Universal Skills Manager

This skill empowers the agent to act as a centralized skill manager for AI capabilities. It discovers skills from multiple sources — SkillsMP.com (curated, AI semantic search), SkillHub (community skills, no API key required), and ClawHub (versioned skills, semantic search, no API key required) — and unifies skill management across multiple AI tools (Claude Code, Gemini, Anti-Gravity, OpenCode, Cline, Cursor, etc.), ensuring consistency and synchronization.

When to Use This Skill

Activate this skill when the user:

• Wants to find or search for new skills.
• Wants to install a skill (from a search result or local file).
• Wants to sync skills between different AI tools (e.g., "Copy this Gemini skill to OpenCode").
• Asks to move or copy skills between scopes (User vs. Project).
• Mentions "Google Anti-Gravity", "OpenCode", or "Gemini" in the context of skills/extensions.
• Wants to package this skill for claude.ai or Claude Desktop (ZIP upload).

Supported Ecosystem

This skill manages the following tools and scopes. Always verify these paths exist before acting.

claude.ai / Claude Desktop (ZIP Upload Required):

Platform	Installation Method
claude.ai	Upload ZIP via Settings → Capabilities → Upload Skill
Claude Desktop	Upload ZIP via Settings → Capabilities → Upload Skill

Note: claude.ai and Claude Desktop don't have access to local environment variables. Use the "Package for claude.ai/Desktop" capability (Section 5) to create a ZIP. Embedding an API key is optional — SkillHub and ClawHub search work without one. If you do include a key, do NOT share the ZIP publicly (see Section 5 for credential safety guidance).

IMPORTANT - Universal Skills Manager Platform Limitations:

This skill (Universal Skills Manager) requires network access to call the SkillsMP API, SkillHub API, ClawHub API, and GitHub. Handle these scenarios:

• If user asks to package/ZIP the Universal Skills Manager itself for claude.ai: Tell the user: "The Universal Skills Manager won't work on claude.ai because it requires network access to call the SkillsMP API, SkillHub API, ClawHub API, and GitHub APIs. claude.ai's code execution environment doesn't allow outbound network requests. However, I can package OTHER skills for claude.ai upload - those will work as long as they don't require network access."

• If user wants to try the Universal Skills Manager on Claude Desktop: Tell the user: "Claude Desktop has network access capabilities, but there is a known bug where custom domains added to the 'Additional allowed domains' setting are not included in the network egress JWT token. This means the skill cannot reach the required APIs even after whitelisting them.

  Required domains (for when the bug is fixed):

  • skillsmp.com (for SkillsMP skill searches)
  • skills.palebluedot.live (for SkillHub skill searches)
  • clawhub.ai (for ClawHub skill searches and direct file downloads)
  • api.github.com and raw.githubusercontent.com (for skill downloads from GitHub)

  Workaround: Use Claude Code CLI instead, which has unrestricted network access and works with all three skill sources. You can install via: curl -fsSL https://raw.githubusercontent.com/jacob-bd/universal-skills-manager/main/install.sh | sh -s -- --tools claude"

(Note: If a tool uses a different directory structure, ask the user to confirm the path, then note it for future reference.)

Core Capabilities

1. Smart Installation & Synchronization

Trigger: User asks to install a skill (e.g., "Install the debugging skill" or "Install skill ID xyz").

Procedure:

1. Identify Source:

   • If from SkillsMP search result: Use the githubUrl from the API response
   • If from SkillHub search result: Fetch skill details via /api/skills/{id} to get skillPath and branch, then construct GitHub tree URL
   • If from ClawHub search result: Use the slug to fetch content via ClawHub's /file endpoint (see Section C below)
   • If from skill name/ID: Search available sources (SkillsMP, SkillHub, and/or ClawHub) to find the skill
   • If local: Identify the source path

2. Verify Repository Structure (CRITICAL):

   • Before downloading, browse the GitHub repo to confirm the skill folder location
   • Use GitHub API to list directory contents: GET /repos/{owner}/{repo}/contents?ref={branch}
   • Look for folders containing SKILL.md - this is the actual skill directory
   • Common patterns: skill/, skills/{name}/, root level, or custom folder names
   • Confirm the correct path before generating the download URL

3. Download Using Helper Script:

   • Use install_skill.py (located in this skill's scripts/ folder):

   python3 ~/.claude/skills/universal-skills-manager/scripts/install_skill.py \
     --url "https://github.com/{owner}/{repo}/tree/{branch}/{skill-folder}" \
     --dest "{target-path}" \
     --dry-run  # Preview first, then remove flag to install
   

   • The script handles: atomic install, validation, subdirectories, safety checks
   • Safety feature: Script will abort (exit code 4) if destination is a root skills directory
   • Update detection: If skill exists, shows diff and prompts for confirmation
   • Security scan: The install script automatically scans downloaded skills for security threats (invisible characters, data exfiltration, prompt injection). Review any findings before proceeding.

4. Determine Primary Target:

   • Ask: "Should this be installed Globally (User) or Locally (Project)?"
   • Determine the primary tool (e.g., if user is in Claude Code, Claude is primary)

2. The "Updates & Consistency" Check

Trigger: User modifies a skill or asks to "sync" skills.

Procedure:

1. Compare: Check the modification times or content of the skill across all installed locations.
2. Report: "The 'code-review' skill in Gemini is newer than the one in OpenCode."
3. Action: Offer to overwrite older versions with the newer version to ensure consistency.

3. Skill Discovery (Multi-Source)

Trigger: User searches for skills (e.g., "Find a debugging skill" or "Search for React skills").

Procedure:

1. Discover API Key and Select Source:

   • Step 1 - Environment Variable: Check $SKILLSMP_API_KEY

     printenv SKILLSMP_API_KEY
     

     If set and non-empty, use SkillsMP as the primary search source. Note: Use printenv (not echo $VAR) — it queries the process environment directly and is more reliable across shell contexts.

   • Step 2 - Config File: Check for config.json in this skill's directory

     # Look for config.json in skill directory (path varies by tool)
     cat ~/.claude/skills/universal-skills-manager/config.json 2>/dev/null
     

     If skillsmp_api_key field has a non-empty value, use SkillsMP as primary source.

   • Step 3 - Source Selection: If no API key found, present the user with a choice:

     "I don't see a SkillsMP API key configured. You have three options:

     A) Provide your SkillsMP API key (get one at skillsmp.com) — curated skills with AI semantic search

     B) Search SkillHub's open catalog — community skills, no API key needed

     C) Search ClawHub — versioned skills with semantic search, no API key needed

     Which would you prefer?"

     • If user chooses A: Collect key, validate it (see below), store in memory for this session, proceed with SkillsMP
     • If user chooses B: Proceed with SkillHub search (no key needed)
     • If user chooses C: Proceed with ClawHub search (no key needed)

   • Key Validation: SkillsMP API keys always start with sk_live_skillsmp_. If the user provides a key that does not match this prefix, reject it immediately:

     "That doesn't look like a valid SkillsMP API key. Keys start with sk_live_skillsmp_. You can get one at https://skillsmp.com — or choose SkillHub/ClawHub search instead (no key needed)."

   • Security: Never log, display, or echo the full API key value.

   Note for claude.ai/Desktop users: Environment variables are not available. Use the "Package for claude.ai/Desktop" capability (Section 5) to create a ZIP with your API key embedded, or provide your key when prompted.

4. Skill Matrix Report

Trigger: User asks for skill report/overview (e.g., "Show my skills", "What skills do I have?", "Skill report", "Compare my tools").

Procedure:

1. Detect Installed Tools: Check which AI tools are installed by verifying their user-level skills directories exist:

   # Check each tool's skills directory
   ls -d ~/.claude/skills 2>/dev/null && echo "Claude: ✓"
   ls -d ~/.codex/skills 2>/dev/null && echo "Codex: ✓"
   ls -d ~/.gemini/skills 2>/dev/null && echo "Gemini: ✓"
   ls -d ~/.gemini/antigravity/skills 2>/dev/null && echo "Antigravity: ✓"
   ls -d ~/.openclaw/workspace/skills 2>/dev/null && echo "OpenClaw: ✓"
   ls -d ~/.cursor/skills 2>/dev/null && echo "Cursor: ✓"
   ls -d ~/.config/opencode/skills 2>/dev/null && echo "OpenCode: ✓"
   ls -d ~/.roo/skills 2>/dev/null && echo "Roo: ✓"
   ls -d ~/.config/goose/skills 2>/dev/null && echo "Goose: ✓"
   ls -d ~/.cline/skills 2>/dev/null && echo "Cline: ✓"
   

2. Collect All Skills: For each detected tool, list skill folders:

   find ~/.{claude,codex,gemini,gemini/antigravity,openclaw/workspace,cursor,config/opencode,config/goose,roo,cline}/skills -maxdepth 1 -type d 2>/dev/null | \
     xargs -I{} basename {} | sort -u
   

3. Generate Matrix Table: Create a markdown table where:

   • Rows = skill names (deduplicated across all tools)
   • Columns = only tools that are installed on the system

5. Package for claude.ai / Claude Desktop

Trigger: User wants to use this skill in claude.ai or Claude Desktop (e.g., "Package this for claude.ai", "Create a ZIP for Claude Desktop", "I want to upload this skill to claude.ai", "Prepare skill for web upload").

Procedure:

1. Explain the Process: "I'll create a ZIP file with this skill ready for upload to claude.ai or Claude Desktop. Since cloud environments don't have access to your local environment variables, I can optionally embed your API key in the package. Note: the API key is optional — SkillHub and ClawHub search work without one."

2. Validate Frontmatter Compatibility (CRITICAL — do this BEFORE packaging): Run validate_frontmatter.py to check the SKILL.md against the Agent Skills spec:

   # Validate only (report issues)
   python3 scripts/validate_frontmatter.py /path/to/SKILL.md
   
   # Validate and auto-fix (overwrites file)
   python3 scripts/validate_frontmatter.py /path/to/SKILL.md --fix
   
   # Validate a ZIP file
   python3 scripts/validate_frontmatter.py /path/to/skill.zip --fix
   

   The script checks for unsupported top-level keys, nested metadata, non-string metadata values, and field length violations. With --fix, it automatically moves unsupported keys into metadata, flattens nested objects, and converts values to strings. Tell the user what was fixed. See Operational Rule 5 for the full spec.

3. Collect API Key (Optional):

   • Ask: "Would you like to include your SkillsMP API key for curated search? This is optional — SkillHub and ClawHub work without a key. If you skip this, the packaged skill will still work for SkillHub and ClawHub searches."
   • If user wants to include a key:
     • Ask: "Please provide your SkillsMP API key. You can get one at https://skillsmp.com"
     • Wait for user to provide the key
     • Validate: Key must start with sk_live_skillsmp_. If invalid, reject and re-prompt or offer to skip.
     • Security: Do not echo or display the key back to the user
   • If user skips, create the ZIP without config.json
   • Credential safety warning (IMPORTANT — always display this if a key is included):

     "Security note: This ZIP will contain your API key in plain text. Please follow these precautions:

     • Do NOT share this ZIP publicly, post it online, or commit it to version control
     • Do NOT distribute this ZIP to others — each user should package their own
     • Use a scoped/least-privilege key if your provider supports it

Operational Rules

1. Structure Integrity: When installing, always ensure the skill has its own folder (e.g., .../skills/my-skill/). Do not dump loose files into the root skills directory.

2. Conflict Safety: If a skill already exists at a target location, always ask before overwriting, unless the user explicitly requested a "Force Sync."

3. OpenClaw Note: OpenClaw may require a restart to pick up new skills if skills.load.watch is not enabled in openclaw.json. Warn the user of this after installation.

4. Cross-Platform Adaptation:

   • Gemini uses SKILL.md.
   • Cline uses the same SKILL.md format with name and description frontmatter. The name field must match the directory name. No manifest generation required. Note: Cline also reads .claude/skills/ at the project level, so Claude Code project skills work in Cline automatically.
   • If OpenCode or Anti-Gravity require a specific manifest (e.g., manifest.json), generate a basic one based on the SKILL.md frontmatter during installation.

5. claude.ai / Claude Desktop Frontmatter Compatibility Check: When a user wants to upload or package a skill for claude.ai or Claude Desktop, validate the SKILL.md frontmatter against the Agent Skills specification. Claude Desktop uses strictyaml (not standard PyYAML) which rejects ambiguous YAML constructs like block scalars. It will reject non-compliant skills with "malformed YAML frontmatter" or "unexpected key" errors.

   Allowed top-level frontmatter fields (Agent Skills spec):

   Field	Required	Constraints
   name	Yes	Max 64 chars, lowercase letters/numbers/hyphens only, must match directory name
   description	Yes	Max 1024 chars. No angle brackets (< or ). Avoid literal block scalars (`

Available Tools

• bash (curl): Make API calls to SkillsMP.com, SkillHub (skills.palebluedot.live), and ClawHub (clawhub.ai); fetch skill content from GitHub or ClawHub directly.
• web_fetch: Fetch skill content from GitHub raw URLs, SkillHub API, or ClawHub API (alternative to curl).
• read_file / write_file: Manage local skill files.
• glob: Find existing skills in local directories.

Implementation Details

Skill Structure

Skills typically contain:

• SKILL.md (required): Main instructions with frontmatter.
• Reference docs: Additional documentation files.
• Scripts: Helper scripts (Python, shell, etc.).
• Config files: JSON, YAML configurations.

Installation Logic

A. Installing from SkillsMP API

1. Fetch Skill Content:

   • Convert githubUrl to raw content URL:

     Input:  https://github.com/{user}/{repo}/tree/{branch}/{path}
     Output: https://raw.githubusercontent.com/{user}/{repo}/{branch}/{path}/SKILL.md
     

   • Fetch the SKILL.md content using curl or web_fetch

2. Create Directory:

   • Use skill name from API response for directory: .../skills/{skill-name}/
   • Example: .../skills/code-debugging/

3. Save SKILL.md:

   • Write the fetched content to SKILL.md in the new directory
   • Preserve the original YAML frontmatter and content

4. Handle Additional Files (Optional):

   • Check if GitHub repo has additional files (reference docs, scripts)
   • Optionally fetch and save them to maintain complete skill package

5. Confirm:

   • Report: "Installed '{name}' by {author} to {path}"
   • Show GitHub URL and stars count
   • Offer sync to other AI tools

B. Installing from SkillHub

1. Fetch Skill Details:

   • Use the skill's id from the search result to get full details:

     curl -X GET "https://skills.palebluedot.live/api/skills/{id}"
     

   • IMPORTANT: The id field (e.g., wshobson/agents/debugging-strategies) does NOT map to the file path within the repo. You MUST use the detail endpoint to get the actual skillPath and branch.
   • Extract from response: githubOwner, githubRepo, branch, skillPath

2. Construct GitHub URL:

   • Build the GitHub tree URL from the detail response:

     https://github.com/{githubOwner}/{githubRepo}/tree/{branch}/{skillPath}
     

   • Example: https://github.com/wshobson/agents/tree/main/plugins/developer-essentials/skills/debugging-strategies

3. Download Using Helper Script:

   • From this point, the flow is identical to SkillsMP installation:

     python3 ~/.claude/skills/universal-skills-manager/scripts/install_skill.py \
       --url "https://github.com/{githubOwner}/{githubRepo}/tree/{branch}/{skillPath}" \
       --dest "{target-path}"
     

4. Confirm:

   • Report: "Installed '{name}' from SkillHub to {path}"
   • Show GitHub URL and stars count
   • Offer sync to other AI tools

C. Installing from ClawHub

ClawHub hosts skill files directly (not on GitHub), so the install flow bypasses install_skill.py and fetches content via ClawHub's API.

1. Fetch SKILL.md Content:

   • Use ClawHub's file endpoint to get the raw SKILL.md:

     curl -s "https://clawhub.ai/api/v1/skills/{slug}/file?path=SKILL.md" \
       -o /tmp/clawhub-{slug}/SKILL.md
     

   • IMPORTANT: This endpoint returns raw text/plain content, NOT JSON. Save the response body directly as the file.
   • The x-content-sha256 response header can be used to verify file integrity.

2. Handle Multi-File Skills (if applicable):

   • If the skill has additional files (scripts, configs), use ClawHub's download endpoint:

     curl -s "https://clawhub.ai/api/v1/download?slug={slug}" \
       -o /tmp/clawhub-{slug}.zip
     unzip -o /tmp/clawhub-{slug}.zip -d /tmp/clawhub-{slug}/
     

   • To check if a skill has multiple files, inspect the detail response from GET /api/v1/skills/{slug} — the latestVersion object may indicate file count.

3. Run Security Scan:

   • Since install_skill.py is bypassed, run the security scanner manually:

     python3 ~/.claude/skills/universal-skills-manager/scripts/scan_skill.py /tmp/clawhub-{slug}/
     

   • Review any findings before proceeding. ClawHub has VirusTotal integration but our scan provides an additional layer.

4. Validate YAML Frontmatter:

   • Verify the SKILL.md has valid YAML frontmatter (name, description fields).
   • If invalid, warn the user and ask whether to proceed.

5. Create Directory and Install:

   • Create the target directory: .../skills/{slug}/
   • Copy all files from the temp directory to the destination:

     mkdir -p {target-path}/{slug}
     cp -r /tmp/clawhub-{slug}/* {target-path}/{slug}/
     

6. Confirm:

   • Report: "Installed '{displayName}' (v{version}) from ClawHub to {path}"
   • Show version info and stars count
   • Offer sync to other AI tools

7. Cleanup:

D. Installing from Local Source (Sync/Copy)

1. Retrieve: Read all files from the source directory.
2. Create Directory: Create the target directory .../skills/{slug}/.
3. Save Files: Copy all files to the new location, preserving filenames.

File Endpoint (GET /api/v1/skills/{slug}/file?path=SKILL.md):

• Returns raw text/plain content (NOT JSON)
• Response headers include x-content-sha256 (integrity hash) and x-content-size (byte count)
• Use version query param to fetch a specific version (defaults to latest)

Key Differences from SkillsMP/SkillHub:

• Direct hosting: ClawHub hosts skill files directly — no GitHub URL construction needed
• Versioned skills: Each skill has explicit version numbers; use version param to pin
• Slug-based IDs: Skills are identified by slug (e.g., self-improving-agent), not GitHub paths
• Semantic search built-in: The /search endpoint uses vector similarity, not keyword matching
• VirusTotal integration: ClawHub scans skills via VirusTotal partnership; moderation field indicates status

Error Handling:

• 404: Skill or file not found
• 429: Rate limit exceeded (120 reads/min)
• 500: Internal server error

Guidelines

• Multi-Source Search: Use SkillsMP as the primary source when an API key is available. Offer SkillHub and ClawHub as alternative or additional sources.
• Prefer AI/Semantic Search: For natural language queries, use SkillsMP /ai-search or ClawHub /search (both support semantic matching). SkillHub only supports keyword search.
• Source Labeling: Always label results with their source ([SkillsMP], [SkillHub], or [ClawHub]) so users can distinguish between sources.
• SkillHub Detail Lookup: When installing from SkillHub, always fetch the detail endpoint first to get the correct skillPath and branch. Never try to parse the id field as a file path.
• ClawHub Direct Hosting: ClawHub hosts skill files directly — use the /file endpoint to fetch content. No GitHub URL construction is needed. Use the slug field as the skill identifier.
• ClawHub Versioning: ClawHub skills have explicit version numbers. Show the version in install confirmations. Use the version query param to pin a specific version if needed.
• Deduplication: When showing results from multiple sources, deduplicate: SkillsMP ↔ SkillHub by full skill ID ({owner}/{repo}/{path}); ClawHub ↔ others by skill name (since ClawHub uses slugs, not GitHub paths).
• Verify Content: After fetching from any source, verify the SKILL.md has valid YAML frontmatter.
• Structure Integrity: Maintain the .../skills/{skill-name}/SKILL.md structure.
• Syncing: After installing a skill, offer to sync (copy) it to other detected AI tools.
• GitHub URLs: For SkillsMP/SkillHub installs, always convert tree URLs to raw.githubusercontent.com URLs for content fetching.
• Security: Security scanning runs on all installs regardless of source (SkillsMP, SkillHub, or ClawHub). SkillHub's securityScore and ClawHub's VirusTotal moderation status are informational only — our own scan_skill.py at install time is authoritative.
